On Location 2015 ASH Annual Meeting of events; the presentation at the ASH annual meeting included results from the second interim analysis. At the time of data presentation, 346 events had occurred over a median followup of 39 months: 197 in the RVD arm and 149 in the AHCT arm. All patients had discontinued treatment, with 66 percent having completed planned therapy; 16 percent experienced disease progression, and 10 percent experienced adverse events (AEs) that led to discontinuation. AHCT was found to improve progression-free survival (PFS; the study’s primary endpoint), with a three-year PFS rate of 61 percent in the transplant arm versus 48 percent in the RVD arm (hazard ratio [HR] = 1.5; 95% CI 1.2-1.9; p<0.0002). B:8.5” Notably, the PFS benefit was observed T:8.25” and uniform across the following subS:7” groups in the AHCT group: age (≤ or >60 years), sex, Ig isotype (IgG or others), ISS The detection of antibody formation is dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to Kogenate FS with the incidence of antibodies to other products may be misleading. 6.2 Postmarketing Experience Because adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following adverse reaction has been identified during post approval use of Kogenate FS: Sensory System – Dysgeusia Immunogenicity – Postmarketing Registries Data from the Research of Determinants of Inhibitor Development (RODIN) study7, French National Registry (FranceCoag)8 and United Kingdom Haemophilia Centre Doctors’ Organisation (UKHCDO)9 registry reported an inhibitor development rate in PUPs for Kogenate FS of 38%, 50% and 35%, respectively, which is comparable to previously-reported inhibitor rates10 for FVIII products. These registry studies show a trend towards an increased risk of inhibitor development in PUPs, as compared to the reference rFVIII product. A survey of Canadian hemophilia centers11 (2005 to 2012) and available data from the European Haemophilia Safety Surveillance (EUHASS) 12 registry from 2009 to 2013, reported an inhibitor development rate in PUPs for Kogenate FS of 42% and 31%, respectively, with no sta tistically significant differences observed across FVIII products. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C. Animal reproduction studies have not been conducted with Kogenate FS. It is also not known whether Kogenate FS can cause fetal harm when administered to a pregnant woman or affect reproductive capacity. Kogenate FS should be given to a pregnant woman only if clearly needed. 8.5 Geriatric Use Clinical studies with Kogenate FS did not include patients aged 65 and over. Dose selection for an elderly patient should be individualized.

Autologous transplantation for multiple myeloma in the era of new drugs: a phase III study of the Intergroupe Francophone Du Myelome (IFM/DFCI 2009 Trial). Abstract #391. Presented at the 2015 ASH Annual Meeting, December 6, 2015; Orlando, Florida. B:11.125” 8.4 Pediatric Use Safety and efficacy studies have been performed in previously untreated and minimally treated pediatric patients. Children, in comparison to adults, present higher factor VIII clearance values and, thus, lower half-life and recovery of factor VIII. This may be due to differences in body composition.13 Account for this difference in clearance when dosing or following factor VIII levels in the pediatric population [see Clinical Pharmacology (12.3)]. Routine prophylactic treatment in children ages 0–2.5 years with no pre-existing joint damage has been shown to reduce spontaneous joint bleeding and the risk of joint damage. This data can be extrapolated to ages >2.5–16 years for children who have no existing joint damage [see Clinical Studies (14)]. 17 PATIENT COUNSELING INFORMATION • Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). • Advise patients to report any adverse reactions or problems following Kogenate FS administration to their physician or healthcare provider. • Allergic-type hypersensitivity reactions have been reported with Kogenate FS. Warn patients of the early signs of hypersensitivity reactions [including hives (rash with itching), generalized urticaria, tightness of the chest, wheezing, hypotension] and anaphylaxis. Advise patients to discontinue use of the product if these symptoms occur and seek immediate emergency treatment with resuscitative measures such as the administration of epinephrine and oxygen. • Inhibitor formation may occur at any time in the treatment of a patient with hemophilia A. Advise patients to contact their physician or treatment center for further treatment and/or assessment, if they experience a lack of clinical response to factor VIII replacement therapy, as this may be a manifestation of an inhibitor. • Advise patients to consult with their healthcare provider prior to travel. While traveling advise patients to bring an adequate supply of Kogenate FS based on their current regimen of treatment. S:10” 8.3 Nursing Mothers It is not known whether this drug is excreted into human milk. Because many drugs are excreted into human milk, caution should be exercised if Kogenate FS is administered to a nursing woman. 15 REFERENCES 1.

Dr. Attal and colleagues also observed a correlation between AHCT and an increased rate of minimal residual disease negativity (80% vs. 65%; p<0.001) and improved time to progression (49% vs. 35%; p<0.001). Significantly more patients in the transplant arm achieved a complete response (59% vs. 49%; P < .01). However, the high three-year post-randomization OS rate (88%) remained similar between study groups. The researchers recorded 41 second primary malignancies in 39 patients (23 in the AHCT arm and 18 in the RVD arm). In the transplant arm, 93 percent of patients underwent AHCT and five toxic deaths occurred during mobilization or in the actual transplant phase (1.4%). A parallel U.S. trial is currently being conducted that will add to these results; though the study has a similar design, patients in both arms are receiving maintenance lenalidomide continuously until disease progression. For now, though, it seems like AHCT will remain the first choice for younger patients with previously untreated MM. “The rate of survival after three years remains high in both study arms,” Dr. Attal said during his presentation of the results. “However, transplantation is already associated with a reduced risk for death due to myeloma. Thus, in the era of new drugs, transplantation should remain a standard of care.” ● T:10.875” 8.2 Labor and Delivery There is no information available on the effect of factor VIII replacement therapy on labor and delivery. Kogenate FS should be used only if clinically needed. stage, standard or high-risk cytogenetics, and response after the three first cycles of RVD (complete response or not). The complete response rate was significantly higher in the transplant arm compared with the RVD arm, the researchers noted (58% vs. 46%, respectively; p<0.01); however, three years after randomization, the “extremely high” rate of overall survival (OS) was similar between the two study groups (p=0.25), the authors noted. ASH Social Media The social media buzz around the ASH annual meeting continued to grow in 2015. A quick look at the use of the #ASH15 hashtag shows some remarkable growth over 2014: TOTAL IMPRESSIONS: 111,432,724 (meaning that more than 100 million people potentially could have seen the hashtag on their Twitter timelines — nearly double last year’s number, when #ASH14 had 57 million impressions.)
